Overlaid Contour Plot - View Model

Displays information to help you determine whether you are using the correct model(s) to create an overlaid contour plot.

Minitab automatically stores the most recent model for a response variable each time you run the analysis. Any model that you previously fit for that response variable is overwritten. For this reason, verify that the currently stored model is the correct model.

Overlaid contour plot does not use the data in the worksheet. Instead, Minitab estimates the contours based on stored models. You must fit a model with two or more continuous variables before you can generate an overlaid contour plot. If you want to include multiple responses, you must fit a model for each response separately. Overlaid contour plots are accurate only if all models represent the true relationships.

Dialog box items

Model Type: This dialog displays only the response surface design models in this worksheet that can create overlaid contour plots.

Response: Choose a response variable. The drop-down list displays all responses that have a model in the active worksheet.

Terms: Displays the terms that are in the last model that you fit for the specified response variable. Use your knowledge of the analysis' history to determine whether the current terms in the model correspond to the correct model. The terms list does not take any input.

Model status: Displays the status of the model associated with the response variable. If the model is out-of-date, you need to re-fit the model before you can create the plot. A model is out-of-date when the data have changed since you fit the model.
